It ALSO is calling loadLibrary0() so
there could be deadlock there. But...this thread is sitting in ClassLoader$NativeLibrary.load,
where it wants to load "awt" (libawt.jnilib it looks like).
So this begs another question: Why is
THIS thread hanging?
It sounds like triggering a full thread-dump
would be the thing to do. I have to confess ignorance and ask: How
do I trigger a full thread-dump?
I will also try to figure out why the
AWTInitializer thread is running... I didn't start it, and I don't know
if it runs by default or anything like that, or it may be triggered somewhere
else in the product.
Thanks again for your help!
